B. E. SGHERMERHORN. MILLING ATTACHMENT FOR VISES.

No. 254,704. Patented Mar. 7, 1882.

UNITED STATES To all whom it may concern Be it known that I, EDWARD E. SOHERMER HORN, of the city, county, and State of New York, have invented a new and Improved Milling Attachment for Vises, of which the following is a full, clear, and exact description.

The object of my invention is to furnish a handy, eificient, and labor saving tool for the shop, for doing the work by hand that is usually done with files.

It consists in a milling-tool carried by adjustable devices, by which it may be attached to a vise or directly to the work, as hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in both figures.

Figure 1 is a side elevation of the milling attachment as applied to a vise. Fig. 2 is a vertical section of the same on line a: 00 of Fi g. 1.

A is a vise, of ordinary character, attached to bench B.

a a are curved bars connected by screw-bolts b b, by which the bars are clamped to the vise, so that they form a yoke for carrying the tool.

0 is a shaft sustained in bearings a, formed in the upper ends of bars a and clamped by a set-screw, c.

d. is a clampingbox fixed on one end of shaft 0.

0 is a vertical post sustained in box d, and formedat one side with dovetail flanges e e, that carry a slide-box, f.

g is a horizontal arm clamped in thQ'bOX f, and formed at its under side with dovetail flanges g 9, that carry a slide-box, h.

tis a tubular screw in the box It, containing an arbor, k, on one end of which is fixed the milling-tool I, while on its other end is attached a hand-wheel, m, by which the arbor and tool are to be turned. The box his formed with a divided portion, q, and fitted with a screw, 7, that serves to tighten the box on the sleeve 2', whereby it is prevented from turning with the arbor.

The post 0 is hollow in its upper portion, and contains a screw, it, that engages the box f, so as to sustain the box and allow of its ver* PATENT OFFICE. 4

tical adjustment. The arm 9 is hollow also, and contains a similar screw, 0, for horizontal adjustment of the box It.

By this construction the parts can be set at any angle required by the work clamped in the vise, and the cutter has a screw-feed in.

three directions-via, a cross-feed by the screwsleeve 7: endwise of the arbor, a feed at right angles to the arbor by the screw 0, and on the post a by screw n.

The screw-sleeve t can be set to hold the cutter at any desired angle without interfering with the free revolution of the arbor. By tightening the screw 1' the sleeve is held stationary.

The cutter, after being adjusted to the work, is to be operated by the hand-wheel m, and, if desired, gearing may be added to vary the speed or to make it self-feeding in its operation.

This attachment is convenient and laborsaving, especially in shops where steam-power is not available.

It is evident that the milling-cutter is superior to a file, for the reason that it can be resharpened as required, and that there is no loss of time in a return-stroke. The adjustments render the attachment universal in its application, and by removing the cutter and substituting a drill-chuck it can be used to do work in drilling that cannot be done by ordinary means.

I do not limit or confine myself to the pre cise form of devices or mode herein described for attaching the milling-instrument to the vise, as such devices or mode may be varied as desired by the constructer without departing from my invention.

Having thus described my invention,Iclaim as new and desire to secure by Letters Patent- 1. The milling attachment consisting of clamping-bars a, shaft 0, having clamping-box d, post 6, slide f, arm g, box it, and tool-arbor 70, substantially as shown and described, combined for operation as set forth.

2. In milling attachments, the combination of'post 6, adjustable box f, arm g, and adjustable box h, carrying the tool-arbor, substantially as shown and described.

3. In milling attachments, the combination box h and screw 1", combined with the screwsleeve i and tool-arbor 70, substantially as and 10 for the purposes set forth.
